The solution of the equation is
Step-by-step explanation:
To simplify an equation of x
- Simplify each side of the equation
- Collect x in side and the numerical terms in the other side
- Find the value of x
∵ The equation is
- Multiply all terms of the equation by 4 to cancel the denominator
of the 2nd term in the left hand side
∵ The equation is
∴ 8x + (1 - x) = 12
∴ 8x + 1 - x = 12
- Add like terms
∴ (8x - x) + 1 = 12
∴ 7x + 1 = 12
- Subtract 1 from both sides
∴ 7x = 11
- Divide both sides by 7
∴
The solution of the equation is

5x2 is first =10 then it would be 10+6=16 and then 16-5=11 hope this helps
Answer:
I , II, and III are true
Step-by-step explanation:
4+2x≤4
Subtract 4 from each side
4+2x-4≤4-4
2x≤0
Divide by 2
2x/2 ≤0/2
x≤0
0 is less than or equal to 0 so I is true
-4 is less than or equal to 0 so II is true
-3 is less than or equal to 0 so III is true

Check the picture below.
bear in mind that, horizonta lines are just y = "some constant", and vertical lines are x = "some constant".
